"The best way to prevent tooth decay is to brush teeth twice daily with a fluoride toothpaste to remove plaque, limit the frequency, and amount of sugary food and drinks consumed in your diet, and see the dentist regularly.
1. Brush for long enough – research indicates that people only brush for 45 seconds
2. Rinse the mouth after brushing – fluoride helps to prevent, control and even stop tooth decay – but rinsing the mouth out dilutes the concentration of fluoride, so SPIT, don't rinse.
3. Brush too soon after eating – as enamel on teeth is softened after eating especially with sugary foods – it's best to wait an hour before brushing which allows the tooth to harden up more.
